or &c. and FiO. 3 a side elevation of Fig.

2 with a portion of the circumference cut away. 1

A is `the mixing-chamber; B, the steam-inlet; C, the oil-inlet; D D, air-inlets; E, the' heating-chamber; F, a coil of pipe therein; G, an oil-pipe leading to the heater; G,a pipe leading from the heater to the Vaporburner; II, the twisting device, and 71 the blades thereof.

In constructing my i mpro ved b urn er I make of suitable material a chamber A. This is provided at points, preferably near the rear end thereof, with the steam-inlet pipe B and an oil-inlet pipe C. These consist, preferably, of pipes or tubes made integral with and opening into the chamber A and connecting with each other, as shown in Fig. l. The chamber A is open at the rear end to allow of the admission of air.

I next construct the tube or pipe I. This is inserted at the rear end of the chamberA and passed inside the oil and steam chamber, and is provided with screw-threads meshing with similar threads on the inside of the steam-chamber, whereby the air-tube maybe moved backward or forward. The steaminlet is beveled on the interior at the point near where the steam issues therefrom into the chamber A, and the pipe I is beveled upon its exterior, so that as it is screwed back and forth by means of a suitable hand-wheel J the Size of the opening through which the steam is to issue may be increased or diminished at pleasure. Thc tube I is open at both ends, and the force of the steam passing through the opening K will act as a siphon to draw air in through the end of the tube I. IVhen this tube I is screwed into place, it cuts off direct communication between the steaminlet and the oil-inlet, and therefore to allow `of the passage of oil I provide the tube with a number of holes or perforations L, through which the oil may pass.

I nextconstruct whatI termthe heater. This consists of a cylindrical chamber of any suitable dimensions and closed with a screwcap at either end. Inside of this I provide a coil of pippe connected with the boiler to allow steam to pass through the same. The end of this coil projects out at the lower end of the heater and the Water of condensation may be allowed to pass off in this way. The oil lis introduced into the heater by means of vvthepipe C and passes by means of another pipek G from the heater into the burner, though the pipe G may of course be omitted and the heater attached directly tothe burner.

I then construct what I have denominated a twister. This consists of a flat ring I-I,

preferably made of brass and of suitable diameter to iit closely in the front end of the burner. This ring is provided with a series of radial blades h, which, as shown more particularly at Fig. 3, are made twisting or curving, like the blades of ascrew or of a fanwheel, so that as the mixtureA ofI steam, air, and vapor passes outy of the burnerit willbe given a swirling or rotary motiongand be thoroughly mixed and distributed in the iirechamber. 1

In operation the front end of the burneris inserted into the fuel-door; or, if desired, a door maybe made provided with an opening,

through which the muzzle of the burner may passintothe fire-boX,theburnerbeingattached to the outside of the door and swinging with it. Steam is then introduced through the pipe B, and passing ont through the opening K draws air through the pipe Iv and oil through the inlet C. The oil and steam and air pass into the chamber A, and, mixing therein with additional air drawn through the rear end of the burner, pass through the twister into the firechamber, where the mixture may be ignited andlburned. Steam is also admitted from the boiler into thc coil F, so that the oil contained IOO the admission of air, a steam-inlet pipe B and an oil-inlet pipe C integral with such 15 chamber, an air-inlet tube I, connected by suitable perforations with the oil-inlet tube and moved in one direction or the other to increase or diminish the size of the steam-inlet,

and a heating-chamber E, connected with the zo oil-inlet pipe, substantially as described.
